    Abstract: PROBLEM TO BE SOLVED: To provide a method for enhancing the capacity of a urea plant capable of enhancing the respective capacities of a high-pressure synthesis zone and a urea recovery zone alone.SOLUTION: In the provided method for enhancing the production capacity of urea overall, a melamine plant is additionally installed within an urea plant including: a compression zone of carbon dioxide and ammonia provided as raw ingredients; a high-pressure synthesis zone of urea; a urea recovery zone for forming a molten urea; and, optionally, a granulating zone. The additional melamine plant is installed so as to feed, entirely or partially into the melamine plant, the molten urea obtained from the urea recovery zone of the urea plant and to return, entirely or partially to the high-pressure synthesis zone and/or urea recovery zone of the urea plant, a residual gas from the melamine plant.

    Abstract: PROBLEM TO BE SOLVED: To provide a process for increasing the capacity of a urea plant including a compression section, a high-pressure synthesis section, a urea recovery section in which a urea melt is formed, and optionally a granulation section.
    SOLUTION: By the additional installation of a melamine plant to the urea plant, a urea melt from the urea recovery section of the urea plant is fed wholly or partly to the melamine plant, and the residual gases (containing carbon dioxide and ammonia) from the melamine plant are returned wholly or partly to the high-pressure synthesis section and/or the urea recovery section of the urea plant, whereby the production capacity of urea is increased.
